The latest version of SD is now available on SIMTEL20 as:
MICRO:<CPM.DIRUTL>SD.77ASM (source code)
SD.77COM (COM file stored in ITS binary format)
SD.77DOC (complete documentation)
SD.77INF (short description of features)
SD-77 works automatically with any number of disk drives, up to
16. If a disk has been left out of a drive, the program passes
that drive and continues. It can be intentionally set to work
with a specified number of drives, however.
SUMMARY OF OPTIONS:
B>SD $U4ADL (etc.)
A - All user areas allowed, usually 0-15, less on RCPM systems
C - Clear screen (if activated for your CRT)
D - All disks starting with 1st available (usually A:)
F - Makes a file called DISKMENU.DIR automatically
L - Library list option
N - No pagination, keeps scrolling if more than one full page
P - Printer option - lists to printer
R - Reset disk (perhaps a new one installed)
S - Shows system files (otherwise doesn't)
V - Shows date, version number
U8 - Start with user 8
Using the $D option now automatically starts on the 1st available
drive (usually A:) drive regardless what drive you were on when you
started. It then checks all available drives. Similiarly, using
the $A option will now always start with User 0, unless entered as
$UnA - where n is a valid user number above zero.
The most significant improvement concerns the ability of SD
to search a range of drives (and/or user areas) for a specified
file. This capability is patterned after FILE.COM. Using the D
option automatically starts searching on drive A and all subse-
sequent available drives, no matter what drive was in use.
Additionally, using the A option will start the search in user
area 0, even if the current user area is higher.
Any number of drives may be used without resetting any part
of the program. If a disk is not inserted in a particular drive
the program passes that drive and continues checking the rest of
the available drives.
Files may be shown in vertical or horizontal listings,
although this must be set when the program is assembled for a
particular system.
SD-77 has support for .LBR files, (an "L" option to list
their member files); and support for the NZCPR/ZCPR2 "WHEEL"
byte option. (SD-77.COM set up for ZCPR2 use with WHEEL at 3EH.)
Size of library member files are shown in 'k'.
Note that you don't really have to be running NZCPR or
ZCPR2 to use the wheel byte feature, just get the WHEEL program
and add code to BYE to make sure WHEEL byte is cleared when a
remote user logs on, (before entering CP/M).George.Wood%cmu-cs-a@sri-unix.UUCP (11/21/83)
Keith; I noticed an option to sd-77 to get date,version number; how can this be done? does it require zcpr? Which is more recent/better tested/ appropriate for z80s, NZCPR or ZCPR2? What's the difference? George

From: Keith Petersen <W8SDZ@mit-mc> The date,version number option in SD-77 refers to SD's creation date and version number. If I recall correctly it's the V option. The most recent ZCPR is ZCPR2. The latest versions are available via FTP from SIMTEL20. ZCPR 1.0 (the original) is also available there and MAY be a better choice for a small floppy disk system since it does not require any .COM files to support it. In a RCPM (Remote CP/M) environment disk space may dictate your choice. There is little need to go to "NZCPR" because you can easily change the built-in commands of ZCPR to whatever you want. NZCPR is NOT supported by the CCP-GROUP. If you have specific questions about either version of ZCPR, Rick Conn <rconn@BRL> is the one to contact. --Keith
